How To Protect Your Table Tennis Racket

Avoid Water Absorption in Your Paddle

Your table tennis blade is very sensitive to the humidity. I will explain to you what is the moisture content of wood and how to protect and conserve your racket. Table tennis racket is made from wood. As in many different industries that involve the use of wood, your blade will absorb humidity (moisture content of wood). And the humidity will soften your blade and make it less powerful. By absorbing moisture, your blade will expand slightly and start cupping or warping.You can also lose the feeling, the sharp feel of the blade. Up to a certain amount of moisture content, your blade is damaged.


Moisture content EMC

What is the moisture content and EMC? Why is it important to your blade?


EMC = Equilibrium Moisture Content is the amount of moisture your blade absorb at equilibrium, where wood stops absorbing moisture from or bleeding moisture into the surrounding air. At this point, wood has reached a water content equilibrium with its environment and is no longer gaining or losing moisture.

So, EMC is the amount of humidity absorbed by your table tennis blade (mass gained). The EMC is directly related to the humidity and temperature of the place where you live!

Look at the diagram. EMC depends on Relative humidity and the temperature. For example, the blue line is the EMC for 30C, at 60% humidity, your blade will absorb about 10% of moisture. That means, if your blade weight is 90g, it will absorb about 9g. It's huge!

How to Protect Table Tennis Blade

  1. Remember, your table tennis blade doesn't like water or humidity. Never put your blade in a plastic sack like this. I've seen many players put their blades in a sack. It's wrong! because the sack will cumulate and increase the humidity. Look at the top players, they just put their blade in his case without any additional cover.
  2. Because I understand well how important the effect of humidity, on the blade's quality, personally I add the silica gel in the table tennis case to keep my racket in a dry condition. The wood quality of my blade is very good, it gives me a sharp and clear feeling even after several years.
  3. Avoid temperature extremes. Table tennis blades don't like extremes of heat or cold. So don't leave your racket on the dashboard of your car.Don't put your racket in the luggage in the airplane, put it in the hand luggage. It's very cold in the luggage carbine.In winter, don't put your racket in the boot of your car. The quality of the wood decreases quickly.
